285441 divided by 20 
Our goal is to divide 285441 by 20.

Advancing to step 1:
If we divide 2 by 20, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 20

Advancing to step 2:
The number 20 fits into 28 1 times, leaving a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 20 from 28, we get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 20

Going ahead to step 3:
If we divide 85 by 20, we get 4 and a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 14.0
The remainder is 5 after subtracting 80 from 85.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 20

Step 4:
20 can be fit into 54 2 times, resulting in a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 142.0
If we take 40 away from 54, we end up with 14.
Bring next digit (4) of the dividend behind the 14 and repeat the process: 144 / 20

Advancing to step 5:
144 divided by 20 is 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 1427.0
Subtract 140 from 144 to get 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 20

On to step 6:
20 goes into 41 2 times with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 14272.0
Deduct 40 from 41 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
20 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 14272.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
100 divided by 20 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 14272.05
Subtract 100 from 100 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 14272.05
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 14272.05
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 14272.05, with a leftover of 0.0.
